How to remove Qlkm Ransomware and decrypt .qlkm files

What is Qlkm Ransomware

Qlkm Ransomware is a disastrous virus, that uses AES encryption algorithms to encrypt user’s files. After encoding files obtain the following extensions: .qlkm. The malware aims at encryption of personal data, such as documents, photos, videos, music, e-mails. Deep encoding makes those files unapproachable and decryption instruments available today cannot help in most cases. To start automatically each time the OS starts, the cryptographer creates an entry in the Windows registry key that defines a list of programs that start when the computer is turned on or restarted. To determine which key to use for encryption, Qlkm Ransomware tries to establish a network connection with its command server. The virus sends information about the infected computer to the server and receives the encryption key from it. In addition, the command server can send additional commands and modules to the virus that will be executed on the victim’s computer. If the data exchange with the command server was successful, the virus uses the received encryption key (online key). This key is unique for each infected computer. If Qlkm Ransomware was unable to establish a connection with its server, a fixed key (offline key) will be used to encrypt files. Below you can observe the _readme.txt file (ransom note), that virus places in affected folders:

Malefactors demand a $980 fee for decryption (or $490 if paid in 72 hours). The virus can encrypt all files on the victim’s computer, regardless of where they are located. Files on your computer’s internal drives, connected external devices, and cloud storage can be encrypted. Type of the file and its contents are not important for the virus – any file can be encrypted. The only thing is that the virus does not encrypt files located in Windows system directories. Use virus removal tools, featured in the article, to remove the core of the virus. Once, the virus is removed you can try STOP Djvu Decryptor from EmsiSoft, the most comprehensive utility to break Qlkm Ransomware encryption to date.
